Gear F4 Detailed Help Notes
Displays to the screen in text mode two tables of sorted gear
ratios in "gear inches". This is (an ancient) standard
of determining (normalized) gear ratios that dates back
to the days of the high wheeler, (Ordinary or Penny Farthing).
In those days it was simply the diameter of the large driving
wheel. Modern safety bicycles can be related back to the
high wheelers by the gear inch which is equal to the number
of teeth in the front chain ring divided by the number of
teeth in the rear cog and multiply the result by the diameter
of the rear wheel.
The reason two tables are displayed is that the left most
one if for use in figuring out what clusters to buy and how
to customize them. The format of the charts are positionally
sorted to easily show the shifting pattern. If they are
printed in condensed mode then the one on the right can be
cut apart and taped on to your bike (handlebar stem?) for
reference. (Make sure nothing is in front of you before
you glance down at it. Don't study it while riding, save
studying for while you are stopped at a red stop light or
resting. Keep an eye on the road! Lets be careful out
there!)
